• To complete the removal procedure, go to "Completing the parts replacement" on page 164.
Installing or replacing an optical drive
Attention: Do not open your server or attempt any repair before reading and understanding "Safety information"
on page iii and "Guidelines" on page 63.
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied. Your
server has two optical-drive bays. If only one optical drive is installed in the lower bay, the upper bay is
covered by a protective shield. When you install a secondary optical drive, save the removed protective
shield in the event that you later remove the drive and need the protective shield to cover the drive bay.
Attention: An unoccupied drive bay without any other protection might impact the EMI integrity and cooling
of the server, which might result in overheating or component damage. To maintain the EMI integrity and
cooling of the server, install a new optical drive as soon as you remove the failing one or the protective shield.
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or transmitters) are
installed, note the following:
• Do not remove the covers. Removing the covers of the laser product could result in exposure to
hazardous laser radiation. There are no serviceable parts inside the device.
• Use of controls or adjustments or performance of procedures other than those specified herein
might result in hazardous radiation exposure.
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following:
Laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam.
Before you begin, review the following optical drive installation rules:
• The server has two optical-drive bays. If your server has only one optical drive installed, ensure that the
optical drive is installed in the lower bay (optical-drive bay 1). The upper bay is for a secondary optical
• The following table provides information about the recommended power connector and signal connector
on the system board for the installed optical drive. To locate the connectors on the system board, see
"System board components" on page 41.
